VANCOUVER, British Columbia, Dec. 01, 2020 (GLOBE NEWSWIRE) — Endeavour Silver Corp.


(NYSE: EXK) (TSX: EDR)

announces that exploration drilling continues to intersect high-grade gold-silver mineralization in the Melladito and San Bernabe vein systems at the Bolanitos mine in Guanajuato, Mexico. Since drilling resumed in June, a total of 22 holes have been drilled of which 11 holes and 22 mineralized intervals returned high grades over mineable widths (view Melladito longitudinal section

Drill holes BN-40, 42, 57 extend the Melladito vein mineralization further to the north and at depth, drill holes 50, 52, 58 extend the Melladito vein mineralization further to the east and near surface to possibly connect with the San Pablo mine workings, and drill holes 45, 47 extend the Melladito vein mineralization another 200 m north on the other side of the San Ramon and Providencia shafts. The Melladito mineralized zone now measures up to 200 m long by more than 250 m deep, still open at depth and to the north.

An initial three holes were drilled along the San Bernabe vein system highlighted by hole BN-59 which returned

Qualified Person and QA/ QC

– Godfrey Walton, M.Sc ., P.Geo ., Endeavour President, is the Qualified Person who reviewed and approved this news release and supervised the drilling programs in Mexico. A Quality Control sampling program of reference standards, blanks and duplicates is used to monitor the integrity of all assay results. All samples are split at the local field office and shipped to SGS Labs, where they are dried, crushed, split and 250 gram pulp samples are prepared for analysis. Gold is determined by fire assay with an atomic absorption (AA) finish and silver by aqua regia digestion and ICP finish, over-limits by fire assay and gravimetric finish.
